Patent number: 5583171Abstract: Microporous material comprising water insoluble thermoplastic organic polymer and particulate amorphous precipitated silica not only exhibits low particulate emissions during handling and use, but also has a low extactable alkali metal content. Microporous material having these characteristics is especially useful in clean rooms where electronic devices such as integrated circuits are manufactured. Such microporous material may be produced by employing amorphous precipitated silica particles having low alkali metal content as all or a substantial proportion of the amorphous precipitated silica particles constituting the microporous material.Type: GrantFiled: March 31, 1994Date of Patent: December 10, 1996Assignee: PPG Industries, Inc.Inventors: Richard A.
